Mouse DPI Calculator

Compute effective DPI (eDPI) as DPI × in-game sensitivity and, when you change hardware DPI, the matching sensitivity that keeps the same eDPI. Everything is typed math in your browser — there is no mouse access, no driver APIs, and nothing is uploaded to DroidXP, the same local-only stance as APK Analyzer and APK String Extractor. Use results as a starting point, then confirm in-game.

Effective DPI (eDPI)

Enter your mouse DPI (from your software or specs) and the sensitivity shown in one game’s menu. Formula: eDPI = DPI × sensitivity.

Match sensitivity after a DPI change

If you move from one DPI to another and want the same effective sensitivity, use: new_sens = (old_DPI × old_sens) ÷ new_DPI. Valid ranges: DPI 100–32000, sensitivity > 0.

What this calculator does

Competitive and FPS players often talk about DPI (dots per inch the sensor reports) and in-game sensitivity (how the game scales those counts). Multiplying them gives a single number — effective DPI (eDPI) — that is easier to compare when two people use the same game’s sensitivity model. This page does not read your mouse: you type values, and the math runs locally, like unpacking logic staying in the tab on APK Analyzer.

Formulas (linear model)

  • eDPI: eDPI = DPI × sensitivity — use for one title at a time when its menu uses a simple linear scale.
  • Constant eDPI across a DPI swap: new_sens = (old_DPI × old_sens) ÷ new_DPI — keeps DPI × sensitivity unchanged so turn rate stays similar before you fine-tune by feel.

Limits and honest caveats

Different games use different internal scales, yaw, and sometimes non-linear curves. Do not assume eDPI transfers cleanly between Valorant, CS2, Apex, and others without a title-specific converter. Raw input, pointer precision, and acceleration can all shift how movement feels even when the algebra matches — treat outputs as starting points and validate in a practice range.

Privacy

No hardware access, no telemetry payload: numbers you enter stay in your session like text you paste into APK String Extractor. Loading this page only pulls normal static assets from DroidXP.

How to use it

  1. Step 1: Enter mouse DPI and current in-game sensitivity to read eDPI.
  2. Step 2: When changing DPI, fill old DPI, old sensitivity, and new DPI to get a matching sensitivity.
  3. Step 3: Click Copy summary for notes, then adjust in-game and test.

Frequently Asked Questions

Does DroidXP read my mouse or upload DPI settings?

No. This page only multiplies numbers you type — there is no device access and nothing is sent to DroidXP, similar to APK Analyzer staying local.

What is eDPI?

Effective DPI is commonly defined as mouse DPI multiplied by in-game sensitivity when the game uses a linear multiplier. It is a shorthand for comparing setups — not identical across every title.

Can I compare eDPI directly between Valorant and CS2?

Not reliably without game-specific conversion — scales and yaw differ. Use this tool for one game’s linear model at a time, or look up official converters for cross-title matching.

Why does “match sensitivity after DPI change” exist?

If eDPI = DPI × sensitivity stays constant, a higher DPI needs a lower in-game sensitivity and vice versa. The calculator solves for the new sensitivity given your old pair and target DPI.

What if my game uses raw input or acceleration?

OS acceleration and some raw-input paths change how counts map to rotation. Treat results as planning numbers and verify in a training range.

Does this measure cm/360?

No — centimeters per 360° depends on each engine’s yaw and units. This page sticks to DPI × sensitivity algebra unless you add your own constants elsewhere.

Are decimal sensitivities OK?

Yes. Games often store fractional values; enter what your menu shows (use dot as decimal separator).

Same privacy as APK String Extractor?

Yes: inputs stay in the tab. Only normal static assets load from DroidXP like any page.

Will this set my DPI in Windows?

No — vendor software or OS settings change hardware DPI. This is a reference calculator only.

Why do pro lists show both DPI and sens?

Pros cite what they run in-game plus hardware DPI; eDPI compresses that pair into one comparable number when the model is linear.
